GROND - a 7-channel imager
J. Greiner, W. Bornemann, C. Clemens +19
We describe the construction of GROND, a 7-channel imager, primarily designed for rapid observations of gamma-ray burst afterglows. It allows simultaneous imaging in the Sloan g'r'…
XMM-Newton observations of the Lockman Hole: X-ray source catalogue and number counts
H. Brunner, N. Cappelluti, G. Hasinger +4
The Lockman Hole field represents the sky area of lowest Galactic line-of-sight column density N_H=5.7X10^19 cm^-2. It was observed by the XMM-Newton X-ray observatory in 18 pointi…
The XMM-Newton Serendipitous Survey V. Optical identification of the XMM-Newton Medium sensitivity Survey (XMS)
X. Barcons, F. J. Carrera, M. T. Ceballos +53
We present the XMM-Newton Medium sensitivity Survey (XMS), including a total of 318 X-ray sources found among the serendipitous content of 25 XMM-Newton target fields. The XMS comp…
The Evolution of AGN Host Galaxies: From Blue to Red and the Influence of Large-Scale Structures
J. D. Silverman, V. Mainieri, B. D. Lehmer +14
We present an analysis of 109 moderate-luminosity (41.9 < Log L{0.5-8.0 keV} < 43.7) AGN in the Extended Chandra Deep Field-South survey, which is drawn from 5,549 galaxies from th…
Robust quantitative measures of cluster X-ray morphology, and comparisons between cluster characteristics
Yasuhiro Hashimoto, Hans Boehringer, J. Patrick Henry +2
To investigate the relationships between dynamical status and other important characteristics of galaxy clusters, we conducted a study of X-ray cluster morphology using a sample of…
Most hard X-ray selected quasars in Chandra Deep Fields are obscured
J. X. Wang, P. Jiang, Z. Y. Zheng +13
Measuring the population of obscured quasars is one of the key issues to understand the evolution of active galactic nuclei (AGNs). With a redshift completeness of 99%, the X-ray s…
